BOX CONSTRUCTION.

Specification of Letters Patent.

Patented July 14, 1908.

Application led May 9, 1907. Serial No. 372,795.

T0 all whom 'it may concern:

Be it known that I, FREDERICK C. FISHER, a citizen of the United States, residing at Blanchester, in the county of Clinton and State of Ohio, have invented certain new and useful Im rovements in Box Construction, of which t e following is a specification.

My invention relates to the manufacture of boxes and has special reference to the construction of boxes of comparatively light material and more particularly to those formed of pulp board or strawboard although it is applicable to other material.

The chief objects of my invention are to provide a reinforcement for boxes having thin walls so that their strength and durability will be decidedly increased without adding materially to the weight; to furnish means for ap lying the improved construction to boxes ormed of a single thickness of material or to those having structural walls comprising two or more layers of su crimposed plates; and to produce boxes aving proper strength with a minimum amount of material, thus conducing to economy in the manufacture.

Further objects of my improved box construction are to provide a reinforcin strip for the corners that can be readily app ied to boxes constructed of any material and that can be used with or without the coperation of the body or general reinforcement.

I accomplish the above and other minor objects by the use of the mechanical construction illustrated in the accompanying drawing which forms a part of this specification and in which- Figure 1 is a perspective view of a box embodying my improvements; Fig. 2 is a plan view of the material for a box, ready to be molded into form; Fig. 3 is a sectional view on the line 3 3 of Fig. 2. Figs. 4 and 5 are plan and edge views, respectively, of a corner fastening, and Fig. 6 is a sectional view of a piece of box material formed of two plates w1th interposed reinforcing wires.

Referring to the drawing in detail the numeral 10 indicates a section of pulp board in which are inserted at spaced intervals a plurality of reinforcing wires, preferably of metal, said wires being inserted during the process of manufacturing the board and are cut even with the section when the latter is severed from the original sheet. The said wires are arranged to occupy the middle plane of the fabric, so that t ere will be an equal layer of pulp upon each side of the wire. The section 10 is designed to form the sides, top, and bottom of the box, and upon said section is placed a narrower section 12 which forms the inner layer of the bottom and the projecting ends are bent upward to form the ends.

Referring particularly to Fig. 2, the portion 13 forms the bottom, the arts designated 14, 14a, being bent upwar y along the margin of the upper section 12 to form the front and back walls, res ectively, and the broken line 15 indicates t e location of the bend for the flap 16 which serves as the cover of the box when completed. The section 12 is reinforced by wires 18 similar to the wires 11 and inserted in the same manner as previously described, and the rojecting ends 20 are bent upwardly along t e broken line 19 which represents the mar in of the lower plate or section 10. The si es and ends havmg been molded in a rectangular form they are secured in apposition at their junctures by means of a strip of metal 21 of suitable length and having angular notches 22 cut in one margin at intervals to properly correspond with the dimensions of the box. This strip is furnished with prongs 23 which are punched out of the metal at frequent intervals. The strips 21 thus prepared are ap plied to the corners where desired, the prongs being driven into the material and clenched in the usual manner. The notches 22 permit the stri s to bend around the corners and the notche half of the strip is bent at a right angle with the continuous portion and the points or prongs driven into the walls of the box, the said notched portions forming miter joints at the corners giving the structure a neat a pearance.

In Fig. 1 t e box is shown assembled, the cover having been secured at the ends by the strips 21, and where the said cover 16 meets the upper margin of the front wall 14, the parts are firmly bound together by sutures of cord or wire 24 which are passed through holes punched in the margins, and fastened by knotting or twisting.

In Fig. 6 is shown a modified form of construction. In this case the walls are formed of sheets of previously repared material between which are placedp the reinforcing wires 11, and the sheets then secured by gluing in' the case of straw and pulp board or by nails or rivets of Wood when other similar material is employed.

I have shown a box constructed with Wires running transversely to the length of the box and extending entirely around the case, and other wires 18 stretching from the top margins of the ends at right angles to the direction of the wires 11 thus inclosino the entire box in a stron sup orting skeleton frame which is entire y hidJden from view, the double reinforcement of the bottom of the box, and the clenching of the corner strips affording a structure of universal strength and lightness combined, and permitting of a decided saving in labor in manufacturing and assembling.

While I have shown a structure employing a certain number of wires placed in parallel series, it is evident that any number of such reinforcing Wires may be used. It is also obvious that the method of construction herein disclosed may be employed in the manufacture of receptacles of various forms and for a variety of uses and I do not wish therefore, to be limited to the precise details of construction set forth.

Having thus described my invention what I claim as new is A new article of manufacture consisting of a rece tacle formed of two rectangular lates of pu p board having series of paralle reinforcing wires embedded therein, one plate bent to form the sides, top and bottom of the rece tacle, the other plate super nosed upon the Erst plate to form a double bottom the reinforcing Wires of each plate lying at a right angle to the wires of the other plate7 the superposed plate having projecting portions bent to form the ends of the receptacle, said plates being secured at their junctures by metallic strips having angular notches cut in one margin thereof, and provided with intef gral prongs engaging the adjacent margins of the plates.

In testimony whereof I aiiix my signature in the presence of two witnesses.
